Selective LSI Four-Pole Circuit Protection
The ABB SACE Emax 2 E1.2C provides compact air circuit breaker protection for low-voltage networks requiring dependable interruption of overload and short-circuit currents. With a rated uninterrupted current of 800 A, an ultimate breaking capacity of 50 kA at 400 V AC and a short-time withstand capability of 42 kA for 1 second, this configuration combines space-efficient switchboard integration with robust fault-current performance.
The Ekip Dip LSI electronic trip unit provides long-time overload, short-time delayed and instantaneous short-circuit protection. The short-time function allows greater flexibility when coordinating multiple protective devices, helping downstream breakers clear localised faults before upstream protection operates. This LSI configuration does not include integrated earth-fault protection.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Three-phase four-wire electrical distribution systems.
- Commercial building power distribution.
- Industrial feeder and distribution protection.
- Transformer secondary distribution systems.
- Infrastructure and utility installations.
- Systems requiring selective short-circuit protection.
- Switchboards requiring withdrawable four-pole circuit breaker construction.
